Journal ArticleDOI
Microstructural optimization of a zeolite membrane for organic vapor separation.
Zhiping Lai,Griselda Bonilla,Isabel Díaz,José Geraldo Nery,Khristina Sujaoti,Miguel A. Amat,Efrosini Kokkoli,Osamu Terasaki,Robert Thompson,Michael Tsapatsis,Dionisios G. Vlachos +10 more
TL;DR: Comparison with previously reported membranes shows that these microstructurally optimized films have superior performance for the separation of organic mixtures with components that have small differences in size and shape, such as xylene isomers.
Journal ArticleDOI
Synthesis of self-pillared zeolite nanosheets by repetitive branching.
Xueyi Zhang,Dongxia Liu,Dandan Xu,Shunsuke Asahina,Katie A. Cychosz,Kumar Varoon Agrawal,Yasser Al Wahedi,Aditya Bhan,Saleh Al Hashimi,Osamu Terasaki,Osamu Terasaki,Matthias Thommes,Michael Tsapatsis +12 more
TL;DR: Zhang et al. (p. 1684) show that a hierarchical zeolite can be made through a simple process using a single structure-directing agent that causes repetitive branching, which leads to a material with improved transport and catalytic properties.
Journal ArticleDOI
Dispersible exfoliated zeolite nanosheets and their application as a selective membrane
Kumar Varoon,Xueyi Zhang,Bahman Elyassi,Damien D. Brewer,Melissa Gettel,Sandeep Kumar,J. Alex Lee,Sudeep Maheshwari,Anudha Mittal,Chun Yi Sung,Matteo Cococcioni,Lorraine F. Francis,Alon V. McCormick,K. Andre Mkhoyan,Michael Tsapatsis +14 more
TL;DR: The synthesis and structure determination of highly crystalline nanosheets of zeolite frameworks MWW and MFI are demonstrated, which allow them to pack well on porous supports, facilitating the fabrication of molecular sieve membranes.
Journal ArticleDOI
Hierarchical nanofabrication of microporous crystals with ordered mesoporosity.
Wei Fan,Mark Snyder,Sandeep Kumar,Pyung Soo Lee,Won Cheol Yoo,Alon V. McCormick,R. Lee Penn,Andreas Stein,Michael Tsapatsis +8 more
TL;DR: It is demonstrated how a wide range of crystal morphologies can be realized through such confined growth within 3DOm carbon, synthesized by replication of colloidal crystals composed of size-tunable (about 10-40 nm) silica nanoparticles.
Journal ArticleDOI
Zeolite membranes – a review and comparison with MOFs
TL;DR: The latest developments in zeolite membranes are reviewed, with an emphasis on the synthesis techniques, including seed assembly and secondary growth methods, and the latest advancements in MOF and mixed matrix membranes are highlighted.
